17 Claims.

This invention relates to lubricating devices and, more particularly, to lubricating pumps adapted, among other purposes, to service lubricant receiving nipples or fittings.

Heretofore, such lubricating pumps have usually been constructed with a lubricant container formed as a permanent part of the lubricating pump, the container being usually filled by hand from an open can or barrel of lubricant.

Among prior art lubricant pumps, it has been usual for those operating pump parts that may be associated with a lubricant container to be arranged at one side of the container or at an end thereof. No one has proposed to extend the gun parts as a unit through the detachable container. Moreover, so far as I am aware, no one has proposed, prior to my invention, to telescope a supporting cylinder through a lubricant container with which the pump parts are to be associated.

One of the objects of this invention, is to provide inexpensive yet effective pump parts adapted to be easily associated with a container of lubricant in a quick, clean manner, and adapted to cooperate with said container to form an efficient lubricating pump for servicing lubrication fittings.

A further object is to provide, in such a structure, a high pressure lubricating pump adapted to force lubricant under high pressure to lubrication fittings and to provide, in combination therewith, means for supplying lubricant from the container to the high pressure pump.

A further object is to provide, in combination with such structure, means for effectively supporting the sides of the lubricant container and for ironing out any dents or other deformations in the sides of the container.

One feature of the invention relates to an arrangement of the high pressure pump parts enabling them to extend through the container so that the nozzle which is adapted to contact with the fitting extends from one end thereof while the handle for the operation of the pump extends from the other. Furthermore, these parts are united with each other and may be pushed through the container and grease, as a unit, thus completely assembling the pump in a quick and easy manner.

Further objects and features of the invention will be apparent after reading the specification and claims and after consideration of the attached drawings.

In the forms here chosen for illustration, my invention comprises a cylindrical lubricant container having a pump extending concentrically and longitudinally therethrough, the pump l1aving an operating handle extending rearwardly from the container, and a nozzle extending forwardly therefrom. The pump may include a tubular barrel having inlet ports formed therein, 5 and a plunger and a suitable valve both positioned in the bore thereof. In the preferred forms of my invention, a supporting cylinder or sleeve (adapted to telescope through the container and support it) is secured to the pump 10 barrel. Means are also provided for supplying lubricant to the inlet ports. In several modifications shown, atmospheric pressure acting upon an annular follower serves this purpose; but, in other modifications, positive means such as push 15 rods acting upon a piston are provided. The push rods may be adapted for manual actuation by pushing effort, or by some apparatus furnishing a mechanical advantage such as a screw device.

I have shown several embodiments of the invention in the attached drawings, in which:

Fig. 15 is a view, in vertical section, of a pump adapted to be operated somewhat similarly to that shown in Fig. 14.

Referring in detail to the pump shown in Figs. 1 and 2, a container [0 is initially provided with a forward closure II and a rearward closure [2, the forward closure being formed with a knock-out portion 13 which is adapted to be displaced by the relatively sharp front end of a nozzle M which is attached to a barrel i5 of the high pressure lubricant pump. In order to aid in displacing the portion I3, said portion [3 may be formed of relatively soft material or may be integral with the container i0 but provided with a scored outline so that when the sharpened end of the nozzle I4 contacts therewith and the pump barrel l5 rotated, the portion i3 is easily cut and pushed out.

As stated, the front end of the nozzle I4 is relatively sharp, this being easily done inasmuch as the contact face I! is preferably inclined to the longitudinal axis of the nozzle and pump barrel. This inclination is not only for the purpose of aiding in cutting out the portion i3, but is also for the purpose of increasing the range of angles through which the lubricating pump may be applied to a lubrication fitting.

The nozzle i4 is formed with a lubricant pocket [8, and the pump barrel I5 is provided, adjacent to the nozzle [4, with a check valve l9. The barrel I5 has, slidably mounted in the bore thereof, a plunger 2.0 to which is secured a plunger rod 2! extending rearwardly from the barrel and provided at its rear end with a mushroom type handle 22. The handle 22 is formed of a substantially circular flanged disc and is arranged with its general plane substantially at right angles to the longitudinal axis of the rod 2!. Interposed between the rear end of the barrel l5 and the handle 22 is a spring 23, adapted to cause the rod 21 and the plunger 29 to move rearwardly (toward the right) when pressure upon the handle 22 is released. The barrel i5 is shown more in detail in Fig. 6, and will be further described hereafter.

Adjacent to the front end of the cylindrical container Hi, the barrel I5 is formed with a plurality of transverse ports 24 through which lubricant may pass to the interior of the pump barrel l5. The rear end of the barrel I5 is formed with threads 25, onto which there is secured the rear end 26 of a supporting cylinder or sleeve 21 which is adapted to telescope within the container I0, and thus to form a support for the container.

Positioned within the cylinder 21 and surrounding the barrel I5 is an annular follower 28, adapted to rest upon the surface of the lubricant in the cylinder and prevent air from piercing the lubricant, the end 26 being formed with a port 29 through which air may enter the cylinder 2'! under atmospheric pressure to cause the follower 28 to move forwardly (toward the left) and to remain always in contact with the lubricant. The barrel i5 is formed with an enlarged external taper 39 which is forced into the opening formed by the knock-out of the portion i3, and forms a tight fit in said opening.

In assembling the container ID with the other pump parts, the follower 28 is positioned adjacent to the taper 30. Then the cover I2 is removed from the filled container l0 and the nozzle end of the pump barrel is forced through the lubricant and through the knock-out portion l3. Rotation of the barrel i5 may aid in cutting out the portion 3. The cylinder 2'! is then telescoped within the container l0, and the lubricant forces the follower 28 toward the end 26, the trapped air escaping through the opening 29. The taper Si) enters the opening formed by the removal of portion i3 and, when pressed firmly therein, the pump is ready for servicing operation. In practice, I prefer to make the opening, closed by the knock-out l3, of the same diameter as the forward portion of the barrel l5, and form the side walls of the opening with outwardly converging tapers. Then, as the barrel is pushed through the opening, it is not covered with a thick layer of grease; and, when the side walls contact with the taper upon the barrel, they may be expanded slightly to take the form of the tapered portion and insure a tight joint.

By pushing upon and releasing the handle 22, the operator reciprocates the plunger 26, and on the forward stroke traps air and/or lubricant ahead of the ports 24 and forces the same out past the check valve l9. On the return stroke, the lubricant is drawn from the cylinder 27 into the barrel l5, atmospheric pressure causing the follower to be continuously maintained in contact with the lubricant and thus maintaining a continuous supply thereof at the ports 24.

In the pump shown in Fig. 3, a spring ring 3!, on the rear end of the barrel l5, rotatably secures thereto a rear cover 32. The cover 32 is tightly secured to the rear end of the cylinder 33 in any suitable manner as, for example, by flanges as shown. The front end of the cylinder 33 is partly closed by a disc 34, formed with a plurality of spaced openings 35.

Positioned adjacent to the disc 34 and secured to the barrel i5, as by a pressed fit, is a tapered sleeve 36, formed integrally with a disc 3? and having spaced openings 38 adapted to cooperate with openings 35. The disc 31' is adapted to contact normally with the disc 34, and the openings 35 and 38 are adapted at times to register with each other and at other times not to register. The disc 3 is rotatable relatively to the disc 3'! for moving the openings 35 to register and not to register with the openings 38. The barrel I5 is provided, adjacent to the cover 32, with a pin 39 cooperating with a slot (not shown) in the cover 32 to limit rotation of the barrel l5 relative to the cover 32. At one limit of rotation, the holes are in register and, at the other limit, they are out of register.

In preparing this type of pump for servicin operations, assuming that it is empty and that the follower 28 is adjacent to the forward (left hand) end of the pump, a container l0 filled ill , plunger rod 2 i.

with lubricant is telescoped over the barrel l5 and over the cylinder 33. Thus, lubricant is forced into the interior of the cylinder 33 through the registering openings 35' and 33. The follower 28 is moved rearwardly of the pump by pressure of lubricant, the trapped air escaping past the flanged connection between the cylinder 33 and the cover 52 or through the central opening in the cover 32. If desired, a port similar to port 29 shown in Fig. 1 may be provided.

When the container 55 is telscoped to the position shown and the lubricant has all moved into the cylinder 33, the barrel i5 and the container I5 (which is secured to the barrel by friction between the tapered sleeve 35 and the closure I I) are rotated relatively to the disc 34, and this rotation causes the holes 33 to move so as to be out of register with the holes 35. The container i5 is then withdrawn from the cylinder 33 and the lubricant which is trapped within the cylinder 33 obviously remains in the cylinder, while the empty container l0 may be discarded. The pump may then be operated as described above in reference to the form shown in Fig. 1

In Fig. 4, there is shown a part of a pump similar in function to that shown in Fig. 3. However, the cylinder 4!, which corresponds to the cylinder 33, has formed integrally therewith an end closure t2 which is, itself, formed with openings 43 through which lubricant may be forced into the cylinder. These openings are normally closed by means of an annular disc 44%, provided with an annular packing member 15 and urged toward the openings 43 by the spring 46 which bears at one end upon the disc and at the other end upon a flange M, formed by an inturned portion of the closure 42. Instead of a follower such as 28, there is provided a lubricant tight piston 43, normally urged forwardly (to the left) by a spring as. During operation, the lubricant which may be trapped in the cylinder i! is therefore forced to the ports 25.

In filling this form of pump, the container of lubricant is telescoped over the pump parts, in a manner similar to that described above in connection with Fig. l, and the pressure of the lubricant raises the disc 4 against the pressure of the spring so that lubricant may flow in through the openings 43, filling the cylinder 4| and compressing the spring 69. The container may then be withdrawn, whereupon the spring 45 causes the disc M to close the openings 43. Thereafter, lubricant may be pumped out by the operation of the handle, in a manner similar to that described above in connection with Fig. 1. However, the spring 49, operating through the piston t8, continuously tends to urge a supply of lubricant to the ports 25.

The pump shown in Fig. 5 is similar in all ma terial points to that shown in Fig. 1, but differs in details of construction. The container i5 is formed with an integral forward end closure 51, and the barrel 52 of the pump 53 may be turned in, as at 55, to provide a guide for the The rod ill may be provided with projections 55 adapted to limit the rearward movement of the plunger and plunger rod. A spring 23 may be interposed between the portion 5 3, and a collar 55 secured to the rod 25 in any suitable manner. The handle, instead of being of the mushroom type shown in Fig. 1, may be formed as shown at 57. The cylinder 53 may be originally formed with both ends wholly open and may have the rear end closed by a cover 59 screw threaded into the cylinder. The

cover 59 may be secured to the rear end of the barrel 52 by means of a screw El, threaded through a tapped opening 62.

The barrel 52 may be formed of a tubular member and, as stated, the member may have the rear end in-struck, as at 54. A small tapered collar 63 may be secured to the barrel 52 by a press or drive fit and may thus form a shoulder for securing the barrel to the closure 5| of the container 5b. In assembling the parts, the plunger 2%) is inserted in the barrel from the left hand end and the handle from the right hand end, the latter being screwed into the former.

On the other hand, the barrel may be formed similarly to the barrel 95 shown in Fig. 1 and as shown more in detail in Fig. 6. Therein a tubular member or originally having walls of greater thickness than the tubular member shown in Fig. 6, has the exterior surface turned down to form a tubular member with a uniform outer diameter, except for the shoulder 36 and the threaded portion 25. Interiorly, the pipe is drilled to form an enlarged bore 65, concentric with the original bore 65 of the pipe. A bushing 6'5, driven in the rear end of bore 65, provides a guide for the plunger rod. The interior of the tube is threaded as at 68, adjacent to the front end of the bore 85, so that a bushing 69 may be screwed therein, the latter serving to secure the nozzle 54 to the barrel !5.

The operation of the form of the invention shown in Fig. 5 is the same as that shown in Fig. l and the mushroom type handle shown in Fig. 1 may be preferable for most uses. With a single type of lubrication fitting standing at varying angles, the mushroom handle makes the pump very easy to apply and assures a straight thrust for the fitting so as always to make a tight joint. Moreover, regardless of the manner in which the pump approaches the fitting, the mushroom type handle does not present an awkward grip to the operator.

In Fig. 8 there is shown a pump in which no telescopic supporting sleeve is provided for the lubricant container. In assembling the pump for use, the closure i2 is removed from the container i9 and the pump inverted in the manner as described with respect to Fig. 1 until the cap or cover H3 is in the position shown. In Figs. 9 and 10 there are shown two forms of high pressure pump for use with containers of the type shown in Fig. 11. In Fig. 9, the barrel H has the front portion turned down, as at 72, to a smaller exterior diameter than the rear portion 73, and intermediate the portions 72 and 73, there is formed a tapered shoulder M corresponding in function to the shoulders 3b and 53. The interior of the barrel is provided with three concentric bores 75, "1'6 and H, and positioned within the barrel is the plunger 18, to which the handle Si is connected through the plunger rod 79.

In Fig. 19, there is illustrated a high pressure pump which, though differing in details, is similar to the high pressure pump shown in Fig. 9. Therein, the barrel is formed of two separate tubes, one being the tube having a relatively small diameter and the other being the tube 86 having its interior diameter corresponding substantially to the exterior diameter of the tube 85 and having its front end telescoped over the rear end of the tube 35. The two tubes are held in fixed relation to each other by a press or drive fit. The extreme front end of the tube 85 is tapered, as at 87, and transverse bores 83 and 89 are formed through the tubes 36 and 85, respectively, and are held by friction in alignment with each other. The plunger BI is positioned within the tube 85 and has secured to the rear end thereof a plunger rod 92, the latter having its rear end formed as a handle 93, of a slightly different design from that of the handle shown in Fig. 9. The rear end of the tube 86 is closed by a cover 94 having a concentric opening 95 through which the rod 92 passes. Contacting with the rear end of the tube 85 is an annular member or Washer 96 having a circular opening 91 through which the rod 92 passes. Interposed between the washer 96 and a washer 99, secured in any suitable manner to the rod 92, is a spring 98 which has the incidental function of holding the washer 95 against the rear end of the tube 35, but is provided mainly for the purpose of maintaining the plunger 9| and the plunger rod 92 normally in the rearward position shown.

The operation of the pumps shown in Figs. 9 and 10 is the same as that described above in connection with Figs. 1 and 2. However, as there is provided no supporting cylinder for the lubricant container, it is necessary that the container be of sufficient strength and thickness to prevent deformation or that greater care be exercised in handling the container and pump.

In Fig. 11 there is shown one form of container especially adapted to be used with pumps similar to those illustrated in Figs. 9 and 10. The container has a cylindrical portion Illa and a front closure Ila. The rear closure I02 thereof differs from the closure E2 in that it is provided with a central opening I93, adapted to be closed during the shipment and storage of the container by a tab I94. The tab I94 may be pulled off when it is desired to insert a pump, such as one of the pumps shown in Figs. 9 and 10, through the container. There is also provided a follower I95, formed with a central opening I96 through which the pump is adapted to extend. The follower may be like 29 or, if desired, formed of a washer I91, of leather or other suitable material, and a crimped metallic clamp I98 therefor.

The pump shown in Fig. 12 corresponds substantially to that shown in Fig. 8, but differs in certain constructional details therefrom. The container 50 is similar to that shown in Fig. 2 but has a flat front end provided with a larger knock-out. The high pressure pump III is formed with a right angled shoulder H2, instead of a tapered shoulder, and is provided with a threaded portion I I3 on which there is threaded a nut H4, the latter being adapted to coact with the shoulder II2 to clamp the closure No separate plunger is provided, but the plunger rod H5, itself, serves as a plunger, the bore II6 of the barrel being uniform throughout. The rear end of the container 59 is closed by a cover which may be secured in any suitable manner to the rear end of the barrel I I I.

The operation of this embodiment is substantially the same as that described above in connection with the embodiment shown in Fig. 1.

In Figs. 13, 14 and 15, pumps are shown in which means are provided for positively urging the follower or piston outwardly in the container, so as to positively force lubricant to the ports of the high pressure gun. In Fig. 13 there is shown a container I2I having a front closure I22 and formed adjacent to the rear end with a plurality of outwardly extending projections or bosses I23. Within the container I2I there is positioned a follower or piston I24 having a flange I25 which, during shipment or storage of the container, is adapted to be maintained within a cooperating flange I26, formed on the rear end of the container I2I.

The pump barrel I21 is provided with a pair of spaced collars I28 and I29, and two or more push rods I3I extend through both of the collars and have their inner ends bearing upon the plunger I24, thus serving to urge the plunger I24 inwardly. The collar I29 is secured to the outer end of the rods I3I but is slidably mounted on the barrel I21, while the collar I28 is secured to the barrel I2! but allows the rods I3I to slide through openings therein. Thus, it is possible for the operator to push the collar I29 inwardly along the barrel I21 from time to time While operating the pump, and thus, by means of the rods I3I, force the plunger I24 inwardly.

Secured to the collar I28 are a plurality of arms I32 which form a spider contacting as a whole with the rear of the container I2I. Each arm is provided with an inwardly extending projection I33, adapted to coact with a cooperating projection I23 for locking the barrel I2'I within the container I2I.

In Fig. 14, the locking projections I35 are positioned in alignment with a flange I36 into which the flange I25 fits. Thus, the locking projections I3? of the spider I38 need not be as long as those shown in Fig. 13. The rear end of the barrel I39 is threaded, as at MI, and a nut 42 is screwed upon the threads. The nut 42 is adapted to bear upon the rear end of a frame structure I43, provided with inwardly extending fingers I44 which serve in place of the rods I3I shown in Fig. 13.

In Fig. 15, the rear end of the pump barrel is threaded, and the rear ends of the rods I3I are seemed to a nut I4'I, screwed onto the threads I46. The barrel is rotatably mounted in the sleeve I45, which sleeve is otherwise similar to 86 of Fig. 10. The plunger rod I48 is formed with a key-way I49 cooperating with a key I5I, secured within the rear end of the barrel I46. Thus, rotation of the plunger rod I48 causes rotation of the barrel I46 and a consequent translational movement of the nut I41 together with rods I3I, to urge the follower I 24 inwardly, for purposes previously described.

Several embodiments of my invention have been illustrated, disclosed and described. In each there is provided a lubricating pump in which a filled lubricant container is associated with cooperating pump parts, the pump parts being arranged to extend through the container. The pump includes a barrel extending through the container, a plunger in the barrel, a nozzle secured to the front end of the barrel and extending in advance of the container, and a plunger rod secured to the plunger and extending rearwardly from the container for operating the pump. In each embodiment, the pump parts to be associated with the container may be assembled as a complete unit and pushed through the container, and the complete pump thus assembled quickly and easily.

Thus, I have designed several types of inexpensive and efficient pumps in each of which a part is formed by a detachable lubricant container which may be filled in the factory and which may be easily assembled with the other parts of the pump without smearing the operator with lubricant. The pump, thus assembled, is capable of supplying lubricant under high pressure to fittings to be lubricated; and I have provided means, not only for protecting the container against dents or deformations after the gun is assembled, but also for ironing out any dents which may previously have been formed therein.

It is to be understood that the above described embodiments of the invention are for the purpose of illustration only, and various changes may be made therein without departing from the spirit and scope of the invention.
